HB 4125 Summary

• Amends Michigan's Safe Drinking Water Act by adding new definitions to section 2 and creating two new sections (7a and 7b) regarding lead and copper testing requirements.

• Requires water suppliers to sample and test their public water supply annually for the presence of lead and copper, with specific sampling protocols including separate testing pools for residences with lead service lines, copper pipes soldered with lead installed after 1982, and all other residences.

• Mandates that water suppliers notify customers whose water is sampled of test results, specifying state drinking water standards and the actual lead and copper levels found in their samples.

• Requires water suppliers to conduct additional profile testing and issue public notices with test results and household water use advice if testing shows lead or copper concentrations exceeding the action level.

• Requires water suppliers to annually notify customers whose residences are served by lead service lines, providing information about health effects of lead and instructions for safe household water use.
